Which describes the eye of a hurricane?a. brings winds of up to 300 km/h
c. has strong, spinning winds
b. has warm, calm air and light winds
d. has spiraling bands of heavy rain

Answers

Answer 1
Answer:

B

THE EYE OF THE STORM IS CALM
Answer 2
Answer:

Answer:

b. has warm, calm air and light winds

Explanation:

The eye of a hurricane is calm and "peaceful", it's the region with calm weather. But the eyewall is really dangerous, due to its pressure and speed difference. Actually, the eyewall has the most severe winds and weather. Another important characteristic is that the eye has the lower pressure.

So, among the options, b. is the right answer.

b. has warm, calm air and light winds

Which of the following describes the measure of current? a. The quality of the charge flow
b.The rate at which charge flows
c. The ability for something to have a charge flow
d.The potential for a charge to flow

Answers

Current is defined as the rate at which charge flows. The quantity that is current is directly affected by the voltage and the resistance of the circuit, where current is directly proportional to the voltage, and inversely to the resistance.

Among the choices, the correct answer is B.

An equinox occurs whena. neither end of Earth’s axis is tilted toward or away from the sun.
b. the north end of Earth’s axis is tilted away from the sun.
c. the north end of Earth’s axis is tilted toward the sun.
d. Earth’s axis is parallel to the sun’s rays.

Answers

Answer: The correct answer is Option a.

Explanation:

An equinox is defined as an event that occurs when Sun's rays fall on the equator at noon and at an angle of 90°.

The axis of rotation of Earth must be perpendicular to the Sun's rays for this event to occur.

If the axis is titled to some angle even, then equinox will not occur.

Hence, the correct answer is Option a.
A! Good luck on your test!

Why the Higg's Boson was only named after Peter Higgs?

Answers

Because the first person who explicitly predicting that theory is Peter Higgs.

There are a group of scientists who worked together to developed the Higgs Boson ttheory such as Jon Botterworth , but the particle finally named after Peter Higgs out of respect since he's the one who 1st explicitly predict it

 

Answer:

He was among the first to propose its existence.

Explanation:

In July of 2012, physicists found it.  This last boson was named the Higgs, after the British physicist Peter Higgs, who was among the first to propose its existence.

Ninety-nine percent of all the matter that can be observed in the universe exists asA. gases.
B. plasmas.
C. liquids.
D. solids.

Answers

Answer:

B. plasma.  

Explanation:

There are four main states of matter:

1. solid

2. Liquid

3. Gas

4. Plasma

Plasma is a state in which 99% of all matter present in the universe exists. It is highly conducting ionized gas. The electric field and magnetic field dominate the behavior of plasma. Plasma is electrically neutral but the positive and negative particles are unbound.

Plasma is the most common state of matter in the universe.
Plasma, the most abundant phase in the universe...

a graph depicts force versus position. what represents the work done by the force over the given displacement?

Answers

The area under the graph. W = f d cos(theta), so you want the number that is force times displacement, which corresponds to the area under the graph.
